SPINNING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 654,081, dated July 1'7, 1900.

Application filed August 25, 1898. Serial No. 689,486. (No model.)

To (tZZ whom it may concern.-

Be it known that I, PAUL WALLACE, a citi zen of the United States, residing in Phila delphia, Pennsylvania, have invented certain Improvementsin Roving, Spinning, and Doubling Machines, of which the following is a specification.

My invention consists of certain improvements in the spinning-machine for which I obtained Letters Patent No. 398,676, dated February 26, 1889, the objects of my present invention being to provide for spinning upon the bare spindle or upon a cop-tube applied thereto and to simplify the means employed for retarding the yarn, so as to insure the winding of the same upon said tube or spindle. These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which Figure 1 is a vertical section, partly in elevation, of sufficient of a spinning-machine to illustrate my present invention; and Fig. 2 is an enlarged sectional plan view 011 the line c 00 of Fig. 1.

1 represents a vertical tubular shaft or sleeve having at its lower end a step adapted to a bearing 2 in a longitudinal rail or bar 3, the upper portion of said sleeve being free to turn in upper and lower bearings 4 and 5, carried by a longitudinal rail or bar 6, so that the sleeve will rotate steadily in a vertical plane. Secured to this sleeve between the bearings at and 5 is the pulley or whirl 7, which receives the driving-belt, whereby rotative movement is imparted to the sleeve, so that the pull of this belt is resisted by the two bearings, and as the latter are closely adjacent to the Whirl 7 any deflection of the sleeve due to this pull upon it is prevented.

Secured to or forming part of the upper end of the sleeve is a disk or cup 8, the up turned outer portion of which terminates at the upper edge in a flange or ring 9, and mounted so as to slide freely within the sleeve is the spindle 10, upon which spindle or upon a cop-tube applied to the same the spun yarn is to be wound. The lower portion of the spindle 10 is preferably of larger diameter than the upper portion, so as to fit as closely to the interior of the sleeve 1 as is compatible with its free vertical reciprocation therein,the spindle being thus so effectually guided in the sleeve that the proper steadiness of movement of said spindle is insured.

, Below the bearing 5 of the sleeve 1 said sleeve has a vertical slot 11 formed in it, and through this slot passes aset-screw12, where by the lower portion of the spindle 10 is secured to a ring or collar 13, surrounding the sleeve, as shown in Fig. 1, and resting upon an antifriction-washer 14:, which in turn rests upon a bearing on the lifter-rail 15 of the machine, the latter having rising-and-falling mo tion imparted to it by any of the usual .devices, so as to effect the vertical reciprocation of the spindle 1O necessary to effect the proper building of the cop thereon. This implies a constant vertical reciprocation of the lifterrail 15 equal in extent to the nose portion of the cop and a gradual rise of said rail, so as to lift the spindle as the successive layers of yarn are wound upon the nose of the cop, said nose being thus always at the lower end and the cop being built from above downward, as shown in Figs. 1 and 3. There may, if desired, be more than one screw for securing the collar 13 to the spindle, but one will in most cases suffice.

Above the ring 9, at the upper edge of the disk or cup 8, is a flanged ring 16, similar to that employed upon an ordinary ring-andtraveler spinning-frame, this ring having the usual traveler 17 engaging with its inner flange, and a similar traveler 22 is mounted upon the flange 9 of the disk or cup 8. The ring 16 is secured to a base-plate 18, which may in turn be secured to a fixed bar or rail 19 above the bar 6, or it may be secured directly to the latter, if desired. The ring 16, having no motion, is what I term a deadring, while the rotating ring 9 at the top of the rotating cup 8 I term a live-ring}. and in the use of the machine the roving from the feed-rolls passes down and through the traveler 22 on the live-ring and thence up and through the traveler 17 on the dead-ring 16 to the spindle or cop-tube upon which the spun yarn is to be Wound. The spindle 10 and ring 9 rotating at the same rate of speed impart the desired twist to the yarn, while the traveler 17, being retarded by its frictional hold upon the dead-ring 16, holds back the yarn to such an extent that it will he properly wound upon the rotating spindle or coptube in accordance with the rate at which the material is delivered by the feed-rolls.

The strain upon the yarn, however, caused by this backward drag of the traveler 17 is much less than when the yarn passes directly from the cop to the traveler, as in ordinary ringand-traveler spinning, for the traveler on live-ring 9 has a hold upon the yarn at a point close to the traveler on the dead-ring 16. Hence the movement of the latter is efiected with comparatively-little strain upon the yarn.

The size of the live and dead rings is only limited by the distance apart of the spindles in the frame. Hence cops of large diameter spinning the same, as will be readily understood.

Having thus described my invention, I claim and desire to secure by Letters Patent-- The combination in a spinning or doubling machine, of a vertically-reciprocated spindle, a sleeve rotating with said spindle and having a live-ring adjacent to the nose of a cop which is being wound upon the spindle, a traveler on said live-ring, a dead-ring occupying a fixed vertical relation to said live-ring, a traveler on said dead-ring cooperating with that on the live-ring, and means for rotating the spindle and the sleeve, substantially as specified. 7 In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

PAUL WALLACE.
